A 65-nm Mobile Multimedia Applications Processor with an Adaptive Power Management Scheme to Compensate for Variations

In this paper we present the SmartReflex

power management techniques implemented on the OMAP3430 Mobile Multimedia Applications Processor. By using multiple voltage domains, fine grain power domains, split-rail memories, and adaptive compensation, SoC active power reduction of 66% and leakage power reduction of 2~3 orders of magnitude was achieved. OMAP3430 contains more than 150M transistors.
